PNEUMATIC-TIRE RIM.

Specification of Letters Patent.

Application mea January e, 1910. serial No. 536,643.

To all whom 'it may concern:

Be it known that I, SYLVESTER CLINE FORCE, a citizen of the UnitedStates, residing at San Francisco, in'the county of San Francisco andState of California, have invented a new and useful Pneumatic-Tire Rim,of which the following is a specification in such full and clear termsas willen- `able those skilled in the art to construct and use the same.

This invention relates'to a rim for automobile wheels, andits object isto `produce a rimvone side of which may be easily and forcibly removedfrom the wheel.

.Another object of the invention is t -produce.a' tire for the woodenwheel which will lbind the parts thereof tightly and firmly together. f

Another vobject of the invention is to produce a rim;upon which thev.tire may be placed with the smallest amountl of trouble.

and which will hold the tire firmly to the In the drawings, in which thesame numeral of reference is applied to the same portion throughout theseveral views, Figure 1 isa sectional view of rim ap lied thereto, andFig. 2 is a side view o a, wheel having its rim.. applled i thereto, andshowing the rim-removing lugs.

` shrunk on the wheel in addition being provided with bolts 4 which passthrough the flange 5, and through the felly 1, the object bein to-holdthe rim firmly in place on the elly even when the rim may be quite looseon the wheel. The rim 3 is provided with-the usual incurved flange 6 forthe purpose of holding the pneumatic tire 7 in place. -The opposite edgeof the rim 3 is cut on a bevel, asshown at 8, for a purpose which willbe explained later. The opposite side of the pneumatic tire 7 is securedto thewheel by means of a detachable tire securing ring 9, which has aportion at 10 beveled', so that it fits the rim 3 when the a ,pneumatictire, and the felly of a wheel, having the flange 11 is tight againstthe side of the felly. This ring 9 is held in place against tlle fellyby means of a series of nuts 12 on t e vided with flanges 13, which areWide enough to. catch lugs 14. The object of these lugs 1s to providemeans whereby the ring 9 may be forcibly pulled away from the side ofthe wheel. This is accomplished by turning the nuts 12 off the bolts,said bolts being firmly held in place in the felly and in the rim 3 bymeans of the threads thereon, and thus providing the necessaryresistance to' forcibly ull the ring 9 away from the felly. Aft thefelly it is a comparatively easy matter to place the pneumatc tirethereon, since the tire at the portion 8 is of much less diameter thantheoutside of thetire holding flanges; and since the rim adjacent thefelly is beveled, it is really of "much less diameter than the insidediameter of the pneumatic tire.

Having thus described my invention, what I claim as new and desire tosecure by Let In a pneumatic tire holding rim, a wheel, a fellytherefor, Aa rim around said felly said rim having one portion thereofbeveled and having a tire holding flange and another flange in contactwith the felly, a removable flanged ring adapted to fit the beveledportion of the previously mentioned rim and having a tire holdin flangeand a flange in contact with said felly, bolts passing through the`flanges in contact. with the felly, flanged nuts.y to secure theremovable ring and beveledriml/in place on the felly, and lugs carriedby thel removable ring to project over the flanged, nuts, substantiallyas described. J

In testimony whereof I have hereunto set my hand this 23d day ofDecember A. D. 1909, in the presence of the two subscribed witnesses. *l
